Chapter 17, Problem 52A

To determine

To explain: The reason for using convex mirrors as rearview mirrors.

Explanation of Solution

Introduction:

Convex mirrors are the curved mirrors whose reflective surface bulges out. The images formed by convex mirrors are always virtual, diminished and erect, irrespective of the object distance in front of the mirror.

Since the convex mirrors always form a diminished and erect image of an object, it provides a wide field of view to the user. This enables a car driver to see the large traffic area behind the car and also forms a smaller image in comparison to an object. Hence, it is used as a rearview mirror in the cars.

Conclusion:

Convex mirrors provide a wide field of view as it always forms a virtual, erect and diminished of an object.
